In FIGS. 1 and 2, reference numeral 1 denotes a container main body made of a synthetic resin such as vinyl chloride resin. The container main body 1 is substantially cylindrical and has an upper end and a lower end opened, and a peripheral surface. Although the diameter L ₂ of the diameter L ₁ and the lower third upper 2 is substantially the same, the intermediate portion is expanded by radial width L ₃ minutes substantially concentrically around the entire circumference between the upper 2 and lower 3 The expanded diameter portion 4 is formed. An inflow port 5 is provided in the expanded diameter portion 4.

Further, one side portion of the container body 1 is further outward than the expanded diameter portion 4 and has a width dimension L more than the upper portion 2.
_The bulging side portion 6 is formed by bulging for ₄ minutes, and the bulging side portion 6 is formed.
The outer end surface 7 is formed in a substantially flat shape, and an outlet 8 is formed in the outer end surface 7. Further, a short engagement cylindrical portion 9 having a width dimension L ₅ is integrally formed with the cell body 1 from the outflow port 8 toward the inside of the cell body 1 in a substantially horizontal shape.

At the height position of the outer peripheral surface of the expanded diameter portion 4 corresponding to the axis of the inflow port 5, a marked line (not shown) of a color different from that of the grid main body 1 is applied. There is. The height position of this marked line is higher than the height position of the axial line of the outlet 8.

Reference numeral 11 denotes a substantially L-shaped elbow body made of a synthetic resin such as vinyl chloride resin.
Is formed to have a width dimension L ₆ (where L ₆ ≦ L ₄ ), and is arranged in the inner space 12 of the bulging side portion 6 from the outlet 8 to the lower side of the cell body 1. And this elbow body
Reference numeral 11 denotes a substantially cylindrical joint portion 13 that is detachably fitted to the outer peripheral surface of the engaging tubular portion 9 of the container body 1, and extends inwardly of the container body 1 continuously from the joint portion 13. It is constituted by a flat-shaped extension portion 14 which is bent downward from the outflow port 8 at approximately 90 °. Further, a locking step portion 15 for locking the inner end portion of the engaging tubular portion 9 and the like is formed at the inner end portion of the joint portion 13.

Reference numeral 16 denotes an outlet pipe connected to the outlet 8, which is made of a synthetic resin such as vinyl chloride resin and has a diameter-reduced portion 17 formed by reducing the diameter on one end side. And
The outer peripheral surface of the reduced diameter portion 17 is fitted and connected to the inner peripheral surface of the engagement tubular portion 9 of the grid main body 1, and the inner end portion of the reduced diameter portion 17 is connected to the locking step portion 15 of the elbow body 11. It is designed to be locked.

The upper end opening of the container main body 1 is closed by a lid (not shown) which can be freely inserted and removed, and the lower end opening of the container main body 1 is closed by a closing member 18.

Next, the operation of this embodiment will be described.

When manufacturing the basin body 1 by, for example, a blow molding method, first, a pipe (not shown) having a diameter substantially the same as the caliber L _{1 of the} upper portion 2 is heated to soften the basin body 1. It is inserted into a mold (not shown) having an inner shape that is substantially the same as the outer shape. Next, both ends of the pipe are closed with plugs and the like, and compressed air is gradually injected into the pipe to mold a preparatory body (not shown) for the main body of the container. In this case, since the portion corresponding to the inner end opening 21 of the engagement tubular portion 9 is in a closed state in this preliminary container body, this portion is cut and opened.
The basin body 1 is manufactured. In this way, the sill body 1 can be easily manufactured by the blow molding method.

On the other hand, although it is possible to manufacture the container body 1 by an injection molding method, since the container body 1 has a shape in which the diameter of the middle portion is expanded, it becomes difficult to remove the core and the die cost is increased. Is very high, and the manufacturing cost of the container body 1 is high. For this reason, it is preferable to adopt the blow molding method, which has the advantage of being inexpensively manufactured, when manufacturing the main body 1.

Next, the outer peripheral surface of the reduced diameter portion 17 of the outlet pipe body 16 is fitted and adhered to the inner peripheral surface of the engaging cylindrical portion 9 of the thus manufactured rod main body 1. Then, the inner peripheral surface of the joint portion 13 of the elbow body 11 is fitted to the outer peripheral surface of the engaging tubular portion 9, and the elbow body 11 is mounted downward.

At this time, since the bulging side portion 6 is formed by further bulging on one side portion of the basin body 1, and the outflow port 8 is opened in the bulging side portion 6, the bulge body 6 can be used even in a narrow place. Even if the widths L ₅ and L _{6 of the} outlet pipe body 16 and the elbow body 11 connected to the inside 1 in the pipeline direction side become large, the piping work is not hindered.

Next, the lower end opening of the container main body 1 is closed by a closing member 18
Block with to obtain a rainwater basin as a sump.

Next, when installing the rainwater basin,
A drain pipe (not shown) on the downstream side is fitted and connected to the outlet pipe body 16 to install a rainwater basin on the site. Next, a hole is formed in a portion corresponding to the inflow port 5 of the expanded diameter portion 4 of the container body 1 in accordance with the position of the drainage pipe 22 on the upstream side with a hole saw or the like.
At this time, since the marked line is applied to the outer peripheral surface of the expanded diameter portion 4 at a height position corresponding to the axis of the inflow port 5, it becomes easy to position the hole, that is, the inflow port 5 in height.

Then, a packing seal 23 (FIG. 1) is fitted into the bored inlet 5, and the packing seal 23
The drainage pipe 22 on the upstream side is inserted into the basin body 1 so as to project through it, and the excess portion of the drainage pipe 22 inside the basin body 1 is cut into a substantially straight line, and the drainage water is discharged to the inflow port 5. Connect the tubes. At this time, the drain pipe 22 is housed in the inner space 24 of the expanded diameter portion 4, and the inlet 5 is kept liquid-tight by the packing seal 23.

Next, the upper end of the container body 1 is closed by a lid (not shown) which can be freely inserted and removed. Further, when the rainwater basin is buried relatively deep in the ground, a pipe body (not shown) is further connected to the upper end of the basin body 1 and the upper end opening of the pipe body is closed with a lid.

Then, after the rainwater basin is installed, when the drainage flows into the basin body 1 through the outflow port 5 and the volume of water in the basin body 1 increases, the effluent drains from the lower end opening of the extension portion 14 of the elbow body 11. It flows into the elbow body 11 from the portion 14a and flows out to the outlet pipe 16 side via the outlet 8. At this time, since the water level in the basin body 1 is always at the same height as the bottom of the outlet 8, the elbow body 11
The odor on the downstream side is water-sealed by the drainage accumulated below the odor, and the malodor does not leak to the basin body 1 side. In this embodiment, the elbow body 11 functions as a trap.

Further, as described above, the drainage pipe 22 and the elbow body 11 on the upstream side are respectively accommodated in the inner space 24 of the expanded diameter portion 4 and the inner space 12 of the bulging side portion 6 of the container main body 1, Since the effective area in the main body 1 is wide, both the drain pipe 22 and the elbow body 11 are almost invisible when viewed from the upper end of the container main body 1. Therefore, it is not necessary to remove the elbow body 11 when removing the deposits accumulated in the basin body 1, and cleaning can be easily performed. The elbow body 11 is detachably arranged so that the elbow body 11 can be removed and cleaned when the downstream side of the elbow body 11 is clogged.

Further, since the upper end opening of the upper portion 2 of the container body 1 can be formed smaller than the conventional one, the ground surface side can be formed compact and the appearance is improved.

Further, at the installation site, the inflow port 5 can be provided at an arbitrary position of the expanded diameter portion 4 in accordance with the position of the drain pipe 22 on the upstream side. Multiple different types of rainwater pits can be used together, and inventory management becomes easy.

In the above-described embodiment, the description was made on the case where the mark was applied in a color different from that of the sill body 1, but the present invention is not limited to this, and the mark is formed in, for example, a V-shaped groove. You can also

Although the rainwater basin has been described in the above embodiment, the present invention is not limited to this and can be applied to various storage basins.
